Let’s brag about how advanced we are in science; some things still remain secret. One of the best examples of this is the one closest to us, a part of our body. secrets of the brain stands out as. As you know, the scientific evolution that has followed humanity for millions of years is at one point blocked when it comes to the brain and its functioning.

your brain temporary memories how and where it is coded has been one of the most curious questions of scientists for years. But according to a new study, scientists seem to have finally deciphered the “secret code” the brain uses to create this type of memory.

The brain detects the most relevant emotional information in the environment and converts it into a simpler structure.

This type of memory allows people to temporarily retain and modify information for a short period of time. random access memory Also known as. For example, working memory plays a role when we briefly remember the order of numbers by dialing a number while calling a place, or when we ask someone for the address of a restaurant and remember which way to go there while getting to the destination described. to go. The new research in question is pretty good for working memory research. a fundamental step represents.

One theory of working memory is that this memory is stored in the brain in a different way than sensory information from the eye or nose, or long-term memories such as basic information we learn in school. to special “warehouses” Derek Nee, an assistant professor of psychology and neuroscience at Florida State University, argues that such “private repositories” are said to be based on a different theory. not there stands that. In this alternative theory, Nee argues that working memory is essentially “when sensory and motor representations are around us as we relate the past to the future” notes that it is an emerging phenomenon. However, a recent article in Neuron supports both theories. square reading.

Accordingly, working memory seems to be one step ahead of collecting sensory information, rather than thinking about what happens during perception or relying on special memory storage. In other words, the working memory is only free from the environment. most relevant sensory information It collects this information in a relatively simple code.

The brain only stores the relevant information necessary for the task

“For decades [çalışan bellekte] there are indications that what we store may differ from what we perceive” Clayton Curtis, a professor of psychology and neuroscience at New York University, and Yuna Kwak, a doctoral student at the same university, used the expressions of functional magnetic resonance imaging (fMRI), which measures changes in blood flow in different parts of the brain to unravel the mysteries of resolve this memory. brain scan technique they used.

They use this technique to perform a task that takes up their working memory. of nine volunteers In one of the trials, they showed participants a circle of grids or slashes on a screen for about four seconds. Then this graph disappeared and after 12 seconds the participants were asked to memorize the angle of the slashes. In other studies, participants were shown a moving point cloud sliding in the same direction and asked to remember the exact angle of the point cloud’s motion. By asking participants to pay attention only to the direction of the slashes or the angle of motion of the point cloud, the researchers thought their brain activity would reflect only certain features of the graphs. After examining the brain scans, the team found that the results were spot on. as they expected discovered that.

Using computer modeling to visualize complex brain activity, the researchers created a kind of map that shows the peaks and troughs of activity in different groups of brain cells. It can be defined as the activation of brain cells that process visual data in response to stimuli that appear in a specific area of ​​the person’s visual field. ‘recipient fields’ By adding it to their memory model, the team determined how the participants’ brain activity correlated with what they saw on the screen during the memory task. According to this analysis, instead of coding all the finer details of each graph, the brain is just… relevant information required for the task at hand. was saving.

Working memory acts as a bridge between perception and action

When examining topographic maps, researchers found that the brain activity used to encode this information a simple straight line noted that it resembles The angle of the line also corresponded to the orientation of the grids or the angle of movement of the point cloud, depending on which graph was shown to the participants. On the other hand, these line-like patterns of brain activity occurred in the visual cortex, where the brain receives and processes visual information, and in the parietal cortex, an important area for memory processing and storage.

What mattered, however, was not the brain’s use of lines to represent images, according to the researchers. The most important of“Your representation of the grids [veya] of the movement abstracted into something else truth” Nee also said the team’s use of very simple images that don’t fully reflect the visual complexity of the real world is also becoming apparent in the study. restrictive states that it is an element.

However, no “a new idea of ​​what it means to keep something ‘online’ in mind for the future” He writes that he did not change the fact that he gave. Working memory is essentially a bridge between perception and action does its job. About this No, “This work offers an unprecedented look at this mysterious intermediate region between perception and action in identifying a representative format that is not similar to what is being perceived or should be done, but clearly legible from visual cues.” expressions used.
